RESUMEN

BACKGROUND: The incidence of uterine anomalies is approximately 0.5-4.7%. In infertile women, this rises to 6.3%. T-shaped uterine anomalies have been associated with infertility, recurrent implantation failure (RIF), and recurrent miscarriage (RM). Hysteroscopic metroplasty (HM) may improve the reproductive outcomes of such cases. STUDY OBJECTIVE: We assessed the effects of hysteroscopic metroplasty on the reproductive and in vitro fertilization (IVF) outcomes in women with T-shaped uteri. DESIGN: A prospective controlled study. SETTING: A teaching hospital. PATIENTS: The reproductive outcomes of 182 patients with primary infertility (PI), RIF, or RM who underwent hysteroscopic metroplasty to treat T-shaped uteri were prospectively analyzed. INTERVENTIONS: Between January 2017 and April 2021, hysteroscopic metroplasty was performed by a single experienced surgeon. The primary outcome was the live birth rate (either spontaneous or assisted). MEASUREMENTS AND PRINCIPAL RESULTS: In all, 182 patients who underwent bilateral, longitudinal, uterine-lateral wall incisions without complications were included. The clinical pregnancy rates after metroplasty were 50.9% (primary infertility group), 71.4% (RM group), and 39.5% (RIF group). During the 1-year follow-up, 25.5% of patients conceived spontaneously (all groups). CONCLUSION: Hysteroscopic metroplasty should be considered for women with primary infertility, RIF, and RM with T-shaped uteri.

RESUMEN

BACKGROUND: Patients with mosaic Turner syndrome who have normal phenotype and pubertal development may be diagnosed based on karyotype examination which is performed due to recurrent abortion or recurrent implantation failure; but according to the literature review, reproductive and obstetric consequences of these cases are based on case reports. There are contradictory publications on this subject recommending pre-implantation genetic testing (PGT) may be a solution to reduce the high risk for the fetus and perform normal embryo transfer. AIM: In this study, our aim was to evaluate the results of in vitro fertilization and preimplantation genetic diagnosis in patients with low-grade and high-grade mosaic Turner syndrome. METHODS: We collected data of patients between 2012 and 2018 from a single center retrospectively. The study analyzed 36 mosaic Turner syndrome patients, of whom, 10 patients were evaluated as high, 26 patients were evaluated as low-grade mosaic pattern for Turner syndrome. RESULTS: Mean age (35,46±0,87 vs. 36,2 ± 1,85) body mass index (25,26±0,74 vs. 30,8 ± 0,63) baseline follicle stimulating hormone (5,73±0,74 vs. 6,70±1,17) basal luteinizing hormone (4,78±0,43 vs. 4,92±0,99) were similar between two groups. In the high-grade mosaic Turner Syndrome patients, duration of stimulation (7,60±0,16 vs. 8,0 ± 0,28, p<0,001), total gonadotrophin dose (1540,0 ± 165,12 vs. 2046,15± 111,47, p<0,001) and the number of normal karyotype embryos was statistically significantly higher (1,58±0,17 vs. 2,00±0,55, p<0,001). The Pregnancy rates in the low-grade and high-grade mosaic Turner syndrome patients' cycles were 30,8% versus 30%, (p = 0.76) respectively. IVF results were also evaluated by the presence of triploidy were accompanying Turner syndrome or not. In the presence of one or 2 X chromosomes, none of the included in the study could achieve live birth. The most common abnormality in the embryos was monosomy and trisomy of the chromosome13. In 30% of the cases, there were 2 or 3 abnormalities present together. In embryos with 2 abnormal chromosomes, the most common 2 abnormalities were monosomy 13 and trisomy 21, while trisomy 13, trisomy X and monosomy 18 were found in 3 or more abnormalities, respectively. CONCLUSION: In vitro fertilization and Preimplantation genetic diagnose should be considered in the infertility treatment of the patient with mosaic Turner Syndrome.

RESUMEN

This retrospective cohort study aimed to evaluate the effect of hysteroscopy and endometrial scratching (ES) in patients with recurrent implantation failure (RIF) who do not have an intracavity pathology. The authors retrospectively collected data of patients between 2014 and 2019 from a single centre. The study analysed 350 unexplained RIF patients, of whom, 225 underwent hysteroscopy and endometrial scratching, and 125 did not have a hysteroscopy prior to an IVF cycle. Pregnancy rates among post endometrial scratching and no endometrial scratching cycles were 35.6% versus 27.2%, (p = .048), clinical pregnancy rates were 32.9% versus 21.6% (p = .026) and live birth rates were 26.2% versus 19.2% (p = .039). Although it is not possible to distinguish whether hysteroscopy or injury is effective in improving live birth results, the authors thought that endometrial injury with gentle conventional curettage is effective in patients with recurrent implantation failure.IMPACT STATEMENTWhat is already known on this subject? Hysteroscopy and endometrial injury improve pregnancy outcomes in IVF cycles, but definitive conclusions have been uncertain.What do the results of this study add? The study showed that endometrial injury with gentle conventional curettage during hysteroscopy significantly improved the pregnancy rates of RIF patients compared to the non-hysteroscopy group.What are the implications of these findings for clinical practice and/or further research? In cases of recurrent implantation failure, even if hysteroscopy findings are normal, endometrial scratching in the follicular phase increases pregnancy rates compared to the non-hysteroscopy group.

RESUMEN

The role of uterine receptivity and endometrial perfusion in in vitro fertilisation (IVF) remains unclear. In our prospective pilot study, we used a new dynamic tissue perfusion measurement method to evaluate this relationship in humans. A standard ovulation induction and embryo transfer method were applied to all the volunteers. On the day of embryo transfer, dynamic images of the uterus were recorded using colour Doppler ultrasound, and these images were uploaded onto PixelFlux Chameleon Software (GmbH, Münster, Germany). After determining the region of interest (ROI), the average velocity, intensity, and area values for all coloured pixels in the ROI, the tissue resistance index (RI) and the tissue pulsatility index were calculated. Endometrial thickness, morphology and dynamic endometrial perfusion parameters were compared between the clinically pregnant and non-pregnant groups. Endometrial thickness, morphology values and endometrial dynamic tissue perfusion measurements were similar between the groups. This study compared perfusion parameters between clinically pregnant and non-pregnant patients by accurately calculating endometrial tissue perfusion using standard software to establish its relationship with implantation success in IVF treatment.IMPACT STATEMENTWhat is already known about this subject? The relationship between IVF success, endometrial receptivity and perfusion is known. Clear valuations of endometrial receptivity require an endometrial biopsy which may cause endometrial damage to the actual IVF cycle. This problem has led researchers to conduct non-interventional studies. Studies have revealed the value of endometrial thickness, pattern and Doppler examination of endometrial uterine arteries in predicting the success of IVF treatment.What do the results of this study add? This prospective pilot study is the first one to use this programme in humans to evaluate uterine receptivity in IVF. Successful results can be obtained by using computer programmes in tissues where perfusion parameters cannot be measured using traditional colour Doppler ultrasonography. Revealing the relationship between tissue perfusion and IVF success will be more effective and accurate with the development of software technologies.What are the implications of these findings for clinical practice and/or further research? To increase the success of IVF treatment, current and new technological developments, as well as imaging methods should continue to be tested.

RESUMEN

The aim of this study was to evaluate the effectiveness of controlled ovarian stimulation (COS) using the letrozole-supplemented stimulation protocol in breast cancer (BC) patients prior to their cancer treatment. Sixty-one BC patients (Stages 0-3) who were referred to a university IVF unit for fertility preservation (FP) and underwent embryo and/or oocyte cryopreservation between 2008 - 2020 were included in this retrospective study. Time intervals between breast surgery and initial fertility consultation (IFC)/completion of FP procedures were evaluated. COS outcomes were assessed and compared between the early follicular phase (EFP) and the random-start (RS) protocols. The patients' mean age was 33.3 ± 4.9 years. The mean time interval between breast surgery and IFC was 20.6 ± 11 (day, mean ± SD) and from IFC to completion of FP procedure was 14.7 ± 5.3. Overall, 9.1 ± 5.9 mature oocytes were obtained, with a peak serum oestradiol level of 388 ± 358 pg/mL. The number of oocytes obtained (11.5 ± 9.3 vs. 10.9 ± 6.9, p = .9) and maturation rates (84.3 ± 17.5% vs. 89.2 ± 11.7, p = .5) were not statistically different between the EPF and RS protocols. The study results support that oocyte or embryo freezing can be performed effectively in a limited time period with letrozole-supplemented COS protocols before the initiation of oncological treatments in breast cancer patients.Impact statementWhat is already known on this subject? Currently, embryo and oocyte freezing are considered the most established fertility preservation (FP) methods for newly diagnosed cancer patients.What do the results of this study add? This study reports the COS outcomes of newly diagnosed breast cancer patients for FP over a period of twelve years from a single IVF unit. The results support that a considerable number of oocytes can be harvested with letrozole-supplemented COS protocol, which appears to be an effective protocol for BC patients.What are the implications of these findings for clinical practice and/or further research? There is a need for additional studies evaluating long-term follow-up of patients with their pregnancy outcomes.

RESUMEN

Developments in embryo freezing techniques in recent years have increased the chance of pregnancy after frozen embryo transfers. In this study we aimed to compare the pregnancy outcomes between fresh (ET) and frozen-thawed embryo transfer (FET) and to evaluate the benefits of embryo freezing strategy for a woman of advanced age. A total of 513 ET cycles in women over the age of 35 years, including 397 fresh ET cycles and 116 FET cycles were reviewed. Mean age was 37.7 ± 2.91 years in FET cycles and 38 ± 2.8 in fresh cycles (p = .327). The patients undergoing FET cycles had higher oestradiol levels and progesterone levels on the day of trigger in their previous fresh cycles compared to that of fresh ET cycles (1675 pmol/L versus 991 pmol/L; 1.43 pmol/L versus 0.96 pmol/L; p < .005, respectively). Biochemical pregnancy rates (43% versus 32%; p = .048), clinical pregnancy rates (38% versus 29%; p = .030) and live birth rates (30% versus 19.6%; p = .013) were significantly higher in the FET than in the fresh ET over 35 years of age.IMPACT STATEMENTWhat is alreday known on this subject? Ovarian stimulation commonly results in the generation of more embryos than are necessary for the fresh embryo transfer. Therefore, cryopreservation and subsequent replacement of frozen-thawed embryos is an integral part of assisted reproductive technique (ART) programs. As IVF technology improved, embryo freezing was performed to allow subsequent transfer if the fresh cycle was unsuccessful.What do the results of this study add? Clinical pregnancy rates and live birth rates were found to be higher in frozen thawed embryo transfer group compared to fresh embryo transfer group over the age of 35.What are the implications of these findings for clinical practice and/or further research? Frozen thawed embryo transfer seems to be a reasonable and favourable method compared to fresh embryo transfer in patients over 35 years.

RESUMEN

OBJECTIVE: The present study aimed to evaluate reproductive outcomes and determine the predictors of clinical pregnancy and live birth in women with elevated baseline follicle-stimulating hormone (FSH) levels, who have undergone intracytoplasmic sperm injection (ICSI) treatment. METHODS: This retrospective study included 1011 ICSI cycles of women with high baseline FSH levels (> 10 IU/L), from a tertiary university IVF center between 2010 and 2015. Logistic regression analysis was performed to evaluate the prognostic factors of clinical pregnancy and live birth. RESULTS: Among the 1011 ICSI cycles, the clinical pregnancy and live birth rates per oocyte retrieval were 19.5% and 14.3%, respectively. The live birth rates were 21.1% and 1.7% in women aged ≤30 years and those aged ≥40 years, respectively. In addition, the live birth rate was 1.47-fold higher in women from whom >3 oocytes were retrieved, compared to those from whom ≤3 oocytes were retrieved (p=0.047). Logistic regression analysis indicated that the age categories ≤30y, 36-39y and ≥40y, level of baseline FSH (≥20 IU/L) and the ovarian response (≤3 or >3 oocytes retrieved) were significantly associated with live birth. CONCLUSIONS: Our study indicated that age, baseline FSH level, and ovarian response are independent predictive factors for clinical pregnancy and live birth among women with baseline FSH levels >10 IU/L.

RESUMEN

Bilateral tubal ectopic pregnancy is a very rare form of ectopic pregnancy. The incidence is higher in women undergoing assisted reproductive techniques or ovulation induction. We report the case of bilateral tubal ectopic pregnancy. The patient was 30 years old and had a 3-year history of infertility; she was referred to the in-vitro fertilization (IVF) program because of tubal factor infertility. A pregnancy resulted from the transfer of two embryos during an artificial cycle. Despite the increase in ß-hCG values during the follow-up, 22 days after the embryo transfer, the ß-hCG levels were 2,408 U/L and the serum progesterone (P4) level was 10.53 ng/ml. After application with methotrexate, ß-hCG levels did not decrease effectively. Moreover, the sonographic screening revealed a suspicious bilateral tubal focus for ectopic pregnancy. A mini-laparotomy was performed and a bilateral tubal pregnancy was found. In the case of unilateral tubal pregnancy after the transfer of two embryos, the situation of the other tube should be systematically checked and ß-hCG levels should be monitored.

RESUMEN

Abstract Bilateral tubal ectopic pregnancy is a very rare form of ectopic pregnancy. The incidence is higher in women undergoing assisted reproductive techniques or ovulation induction. We report the case of bilateral tubal ectopic pregnancy. The patient was 30 years old and had a 3-year history of infertility; she was referred to the in-vitro fertilization (IVF) program because of tubal factor infertility. A pregnancy resulted from the transfer of two embryos during an artificial cycle. Despite the increase in β-hCG values during the follow-up, 22 days after the embryo transfer, the β-hCG levels were 2,408 U/L and the serum progesterone (P4) level was 10.53 ng/ml. After application with methotrexate, β-hCG levels did not decrease effectively. Moreover, the sonographic screening revealed a suspicious bilateral tubal focus for ectopic pregnancy. A mini-laparotomy was performed and a bilateral tubal pregnancy was found. In the case of unilateral tubal pregnancy after the transfer of two embryos, the situation of the other tube should be systematically checked and β-hCG levels should be monitored.

RESUMEN

OBJECTIVE: This study was performed to explore the possibility that each oocyte and its surrounding cumulus cells might have different genetic expression patterns that could affect human reproduction. METHODS: Differential gene expression analysis was performed for 10 clusters of cumulus cells obtained from 10 cumulus-oocyte complexes from 10 patients. Same procedures related to oocyte maturation, microinjection, and microarray analyses were performed for each group of cumulus cells. Two differential gene expression analyses were performed: one for the outcome of clinical pregnancy and one for the outcome of live birth. RESULTS: Significant genes resulting from these analyses were selected and the top 20 affected pathways in each group were analyzed. Circadian entrainment is determined to be the most affected pathway for clinical pregnancy, and proteoglycans in cancer pathway is the most affected pathway for live birth. Circadian entrainment is also amongst the 12 pathways that are found to be in top 20 affected pathways for both outcomes, and has both lowest p-value and highest number of times found count. CONCLUSION: Although further confirmatory studies are necessary, findings of this study suggest that these pathways, especially circadian entrainment in cumulus cells, may be essential for embryo development and pregnancy.

RESUMEN

Male infertility is correlated with sperm morphology and sperm DNA damage, which are completely different from that of fertile individuals. An accurate sperm DNA damage analysis and ultrastructural examination of the ejaculate provide important support in the clinical evaluation. It is supposed that in the near future, the fertilization rate, pregnancy rate, and miscarriages could be predicted using the combination of these types of tests in assisted reproductive technologies (ARTs). For this purpose, we report a very rare case of an infertile man having short tail sperm. The infertile man and his wife underwent in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI). During this process, we examined the ultrastructure of the ejaculated sperm with transmission electron microscopy (TEM) and calculated the sperm DNA damage with terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and COMET assays. Then, we evaluated the association between sperm DNA damage and embryo quality.

RESUMEN

Ovarian hyperstimulation syndrome (OHSS) is a serious iatrogenic complication that can occur during assisted reproductive techniques. The aim of this study is to investigate the effects of the leukotriene receptor antagonist (montelukast) treatment in prevention of OHSS and compare to cabergoline treatment. Twenty-four immature female Wistar rats were assigned to four groups. Group 1 was the control group. In the remaining three groups, OHSS was induced through ovarian stimulation with gonadotropins. No treatment was given to Group 2. Group 3 was administered a low-dose 100 mg/kg cabergoline treatment and Group 4 was received 20 mg/kg montelukast. Body weight, ovarian weight, vasculary permability (VP), peritoneal fluid vascular endothelial growth factor (VEGF) values and VEGF immune-expression were compared between the groups. Both cabergoline and montelukast prevented progression of OHSS compared to the OHSS group. Body weight, ovarian weight, VP, peritoneal fluid VEGF values and VEGF expression were significantly lower in both cabergoline- and montelukast-treated rats than in those not treated OHSS group. In conclusion, montelukast is an effective option for prevention of OHSS, as well as cabergoline. Montelukast may be a new treatment option to prevent and control the OHSS.

RESUMEN

PURPOSE: Nowadays sperm analysis is used routinely to assess infertile men, but it's predictive value is still restricted. For this reason, new markers are needed for diagnosis and guide treatment. A DNA damage evaluation method, which is easily applicable for routine analysis is described in this paper to provide an important support in clinical evaluation. METHODS: In this study, DNA damage evaluation was planned in infertile males with the COMET assay, a method which is simple, cheap, sensitive and reliable. For this purpose, the sperm DNA damage of normospermic, oligospermic, asthenospermic and teratospermic cases were investigated and the relationship between sperm parameters (sperm count, motility, morphology) and DNA damage was assessed. RESULTS AND CONCLUSION: According to our results we suggest that the factors to blame for sperm DNA damage and semen quality are the same. Also it was found that the infertile males possess substantially more sperm DNA damage than fertile men do. Improving and using the DNA damage evaluation tests seem to improve the results in ART clinics.

RESUMEN

BACKGROUND: The aim of this study is to determine the effects of zinc and/or progesterone via the expression of α v ß 5 integrins and Vitronectins and embryonic stem cell markers during the peri-implantation period. METHODS: Four experimental groups were organized. All subjects were mated with males of the same strain to induce pregnancy; after 5 days, zinc and/or progesterone were administered. Blood levels of zinc and progesterone were determined on the sixth day and endometrial tissues were obtained in order to evaluate the immunohistochemical expression of integrins and embryonic stem cell markers. RESULTS: The αvß5 integrin and vitronectin expression increased in the zinc group compared with the control group and no difference in the progesterone group and zinc + progesterone group. Expression of Klf-4, Sox-2, and c-Myc was found to be increased in the zinc group compared to controls, while no difference was determined between the progesterone, zinc + progesterone, and control groups. Distinctively, expression of the embryonic stem cell marker Oct-4 was increased in all of the experimental groups. CONCLUSIONS: Expression of α v ß 5 integrin, vitronectin, and embryonic stem cell markers might be increased by the administration of zinc. Our results suggest that zinc could be useful in the induction of implantation rates.

RESUMEN

OBJECTIVE: To determine serum and follicular leptin levels in patients using gonadotropin releasing hormone agonist and antagonist in Assisted Reproductive Technology short protocol cycles and to evaluate pregnancy outcomes. MATERIAL AND METHODS: Patients randomly selected to join assisted reproductive technology cycles during February 2004-July 2004 were enrolled in this study. Group 1 consisted of 21 patients receiving r FSH+ GnRH agonists, whereas Group 2 consisted of 34 patients who received r FSH +GnRH antagonists. During the ovulation induction period 5 serum samples were collected (induction day 1, day 3 or antagonist starting day, human chorionic hormone day, oocyte pickup day, and twelfth day of embryo transfer). Follicular fluid samples were collected to be evaluated for leptin, estradiol, prolactin and luteinizing hormone. RESULTS: There was no difference in age, basal FSH, basal LH, and basal E2 between groups. Serum leptin levels were similar in both groups. Also, when each group's serum leptin levels were evaluated according to the presence of pregnancy, there was no significant difference in both groups. When follicle leptin levels were evaluated according to the existence of pregnancy, in both groups the follicle leptin levels were lower in pregnant participants but this difference was not statistically significant. When obesity is defined as body mass index over 26.5, there is a correlation between obesity and leptin levels in Group 2. CONCLUSION: Our results have shown that both agonists and antagonists have similar efficacy and effect in poor responder women. Leptin levels in either groups, whether pregnant or non-pregnant were not statistically different. This result shows the need for more studies on leptin in infertility.

RESUMEN

PURPOSE OF REVIEW: To discuss the relationship between endometriosis and infertility, the impact of endometriosis on assisted reproductive techniques and also the benefits of prolonged use of gonadotropin-releasing hormone analogue before IVF in women with endometriosis. RECENT FINDINGS: The available evidence suggests that endometriosis is strongly associated with infertility. Many studies indicate lower pregnancy and implantation rates even in assisted reproductive cycles in women with endometriosis. It is well known that medical suppression of endometriosis does not appear to be warranted for endometriosis-associated infertility. Prolonged pretreatment with gonadotropin-releasing hormone analogue before IVF has been reported to improve clinical pregnancy rates in infertile women with endometriosis. SUMMARY: Based on the recently published data, infertile women with endometriosis may benefit from long-term pretreatment of gonadotropin-releasing hormone analogue prior to IVF.

RESUMEN

AIM: To examine the effect of premature luteinization on the outcomes in long gonadotropin-releasing hormone agonist cycles. METHODS: Two-hundred and forty-eight patients who had undergone assisted reproductive technology for infertility treatment between 2001 and 2002 were enrolled into the study. The patients were separated into two groups according to P/E2 ratios on human chorionic gonadotropin administration day. Group A consisted of the patients whose P/E2 ratio was 1 (n = 116) and Group B consisted of the patients with premature luteinization of which P/E2 ratio was > 1 (n = 132). The P/E2 ratio calculation was performed as follows: P (in ng/mL) x dagger 1,000/E2 (in pg/mL). The primary outcome measures included oocyte quality, fertilization rates and clinical pregnancy rates. RESULTS: The mean number of mature oocytes retrieved in the groups were 9.5 +/- 4.8 and 6.4 +/- 3.6, respectively, and the difference was statistically significant (P < 0.05). Although the difference between the fertilization rates in Group A and Group B was not statistically significant (P > 0.05), the clinical pregnancy rates seemed to be affected adversely in the Group B patients with premature luteinization (41.4%versus 28%, respectively; P < 0.05). CONCLUSION: Premature luteinization, defined as P/E2 > 1 on human chorionic gonadotropin administration day, in long gonadotropin-releasing hormone agonist cycles seems to adversely affect clinical outcome.

RESUMEN

AIM: To provide a comparison between the follicular response to ovulation induction, and the pregnancy rate of women with a single or two ovaries, undergoing assisted reproductive technology. METHODS: To evaluate the outcome of assisted reproductive technology, 46 treatment cycles in women with one ovary were compared to 123 cycles in women with two ovaries. RESULTS: The mean age of the patients in the two groups were not similar (34.4 +/- 3.8 and 33.1 +/- 4.0, respectively). The one ovary-group had significantly higher mean baseline Follicle Stimulating Hormone levels and required more ampoules for induction. Although the induction period was longer in the one-ovary group, the outcome of the assisted reproductive technology in both groups was similar. The maximum E2 levels on the day of Human Chorionic Gonadotropin administration were significantly lower in the one-ovary group, although endometrial thickness appeared to be the same in both groups. The patients with two ovaries had a significantly higher mean number of mature or immature oocytes aspirated, as well as embryos transferred. Although there was no statistical difference between the two groups following assisted reproductive technology, the pregnancy rate in the two-ovary group was more than double that of the one-ovary group. CONCLUSION: The potential for success after in vitro fertilization is not impaired in women with one ovary.

RESUMEN

AIM: In the present study, we examined the outcome of assisted reproductive technology cycles in patients with or without baseline ovarian cysts following gonadotrophin-releasing hormone analogs administration. MATERIALS AND METHODS: Three-hundred and fifty-six patients who had undergone assisted reproductive technology treatment were enrolled in the study. The patients, all of who had undergone cyst aspiration prior to ovarian stimulation, were grouped into two groups according to the absence or presence of ovarian cysts. These two groups were compared on the basis of the clinical pregnancy rates, the baseline E2 levels, the total follicle stimulating hormone ampules used, the total number of days of induction, the maximum E2 levels, the number of oocytes retrieved, the fertilization rates and the number of embryos available for transfer per controlled ovarian hyperstimulation cycle. RESULTS: The number of ampules used for induction was significantly higher in the cyst group 37.2 +/- 13.0, 32.1 +/- 11.7, respectively, (P = 0.001). The number of total induction days was also longer in the cyst group 9.7 +/- 2.2, 8.9 +/- 1.6, respectively, (P = 0.001). There was no difference between the mean E2 levels measured on the human chorionic gonadotropin administration days (P = 0.339). There was also no difference in terms of the number of oocyte retrieved (P = 0.846). The number of embryos transferred did not differ statistically between the groups (P = 0.233). Finally, there was no significant difference between the groups according to the clinical pregnancy rates 25.3%, 30.7%, respectively, (P = 0.218). CONCLUSION: Baseline ovarian cysts have a negative impact on the quality of ovarian hyperstimulation procedure; however, they have no negative effect on the pregnancy rates in IVF cycles.

RESUMEN

OBJECTIVE: To determine the value of ovarian stromal artery Doppler indices in the prediction of ovarian response in in vitro fertilization-embryo transfer (IVF-ET) cycles. STUDY DESIGN: Forty-five cases were involved in the study. Following controlled ovarian hyperstimulation and detection of at least three follicles > 17 mm in diameter by transvaginal sonography in both ovaries, human chorionic gonadotropin was administered and follicle aspiration performed at the 34th-36th hour. The patients were separated into two groups according to the number of oocytes collected. Group I consisted of 8 (18%) patients who had three or fewer oocytes (low-responder cases); group II consisted of 37 (82%) patients who had 4 or more oocytes (good-response cases). RESULTS: A significant negative correlation was found between both the stromal ovarian artery pulsatility index and the number of aspirated follicles (r = -.31, P = .04) and number of oocytes collected (r = -.32, P = .03). Although there was no significant correlation between the resistance index and number of aspirated follicles (r = .24, P = .12), a significant negative correlation was determined between the resistance index and number of oocytes collected (r = -.30, P = .04). Pulsatility and resistance indices were significantly different between the two groups (1.6 +/- 0.5 and 1.2 +/- 0.5, P = .02, versus 0.7 +/- 0.08 and 0.6 +/- 0.08, P = .03, respectively). CONCLUSION: Blood flow in the vessels that supply blood to the follicles in the ovaries in the early follicular phase correlates significantly with ovarian response.
